public class NonNullableComboBoxModel
The NonNullableComboBoxModel
is a simple class for
ensuring that a JComboBox
will always have an item
selected (if that we start with a non-empty list.) This will
prevent the user from Control-clicking in the list to unselect
the selected item in the JComboBox.
This can be used to guarantee that there is always a selected item in the combo box model. If the user attempts to unselect an item, the previously selected item will remain selected. The selection will be empty only if the combo box model is empty.
